Re: Is read_file() always called after an activity __init__?

At least this is what I'm seeing here – I've just created a 0 size file in my write_file() and now a resume from that journal entry is triggering read_file() every time. You are right again. Perhaps we should add a read_metadata() method? An alternative would be to have a 'datastore-loaded' method, but that would be less consistent with the current API. Hmmm, so if my activity needs it's preferences before it can display anything to the user, potential future lazy loading of the data-store (to try and speed up general activity start-up time) is going to leave folks watching my activity with a blank screen for a lazy while? Ouch. Well, metadata loading shouldn't be as slow as for the user to notice. But if you add this to all the other initializations, it is significant. Also, the user wouldn't see a blank screen, just startup will be (say) 100ms slower than for an activity that can start without reading the metadata. But the determining reason would be that metadata properties other than the custom ones are not preserved across reboots :/ http://dev.laptop.org/ticket/4662 Oooh thanks, double ouch, I hadn't spotted that gotcha yet! I'm getting the distinct feeling I should avoid current metadata interactions by an activity (too flakey and in transition just now) and just create a custom preference like file format, it only needs to store two key/value pairs at the moment, probably will eventually need only half a dozen at the most for future display options. Though I guess even that's still going to be a problem if lazy data-store loading is ever implemented (though every activity that needs to load a file for display will suffer there). Leave the metadata alone for the Journal and lower level activity class behaviours. Pity, metadata looked like a nice solution for storing simple custom activity state information, maybe in update. 2... Right, metadata in journal entries was thought exactly for that. Using some other kind of preferences file may be the best for now. Regards, Tomeu ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

So things like Maths, English, whatever... My thought is that many activities will be started and resumed in a certain class-context and offering such a filter could help them to quickly find related matters. One of our fears here is the proliferation of options within this menu, which could eventually limit its usefulness, and is the reason we chose to limit to some primitive types and the installed activities. A common way to address this problem is to make the menu customizable with user-defined filters and the ability to remove unneeded filters (but keep the option to restore them later). Google mail is an example, where users can create their own tags and set filters to apply them automatically. Indeed. The implied hypothetical at the end of my response alluded to the fact the almost anything is possible, assuming you add additional UI/management tools, but we're trying to find a balance between functionality and management overhead. I'm using Gmail to write this, and their system does work pretty well, but naturally has an entire screen dedicated to both creating labels and assigning filters. We've also discussed the possibility of adding saved searches or the like (there are 15 names for this basic idea...) in the future, but there is a lot of basic functionality left to add before we add this form of meta-functionality. Perhaps the What list is the appropriate place for these saved filters to live, eventually. Thanks for offering that idea. I agree, adding those customized filters to the what category would make a lot of sense. - Eben The usual alternative is folders, as in Moodle. One can imagine that the subject of an activity is actually subjectively defined, and even when it's relatively clear, we might wind up with some for each of math, geometry, trigonometry, algebra, etc. To make a similar functionality available, though, we've chosen to allow developers to supply a list of tags within the .info file for any given activities, which could include several subject related words, as well as more abstract or general terms like game, simulation, or language. We hope that the ability to search by broad terms such as math or games will then turn up a list of appropriately related activities. Having just typed this and then reviewing the wiki, I notice that this part of the spec doesn't appear to be there yet! Can those familiar with this respond about the presence or absence of this capability? If this isn't there, it should get a ticket. It should be a pretty straightforward addition and simple to implement, it seems. Ahhh, that's indeed interesting, I hadn't been aware of this functionality before... Per Eben's question: Does anyone happen to know whether this is already implemented or not? anytime: Here it might make sense to add more informal filters such as 5 grado, 2nd semester or something along these lines. This one is actually much harder to do in a general way. We chose, on purpose, to treat time in the relative sense with respect to the Journal. Instead of seeing a story you wrote on November 28, 2007 you might find a story you wrote 3 months ago. This approach was chosen, in a sense, to internationalize (or perhaps simply generalize) the Journal with respect to time, so that school systems with widely different schedules (some might have class daily for one of every 3 months, for instance) can all take advantage of it. Of course one could also argue that such information could be explicitly added via the tags but I think a more implicit mechanism could potentially make more sense. You can see how, in the former case, the tag model is still implicit, in a sense, when installing an activity. In the latter case, I don't see any good way other than explicit tagging that doesn't have additional UI overhead/management to function. I'm open to ideas here. Mmmm, shouldn't it

Re: Localization of TurtleArt

I wonder if just some scripts to take the text and use cairo to draw it (via inserting the text into SVG files at the right places), might be a way to completely automate the generation of the images that are used. Alternatively, using Cairo (maybe using pango, if we need to support RTL text) to write the text directly onto the images being used inside TurtleArt may be a way to skin this cat, and not have to have a lot of gif's for each language. - Jim On Fri, 2008-02-29 at 08:55 -0500, Walter Bender wrote: As I recall (it was a while ago) ImageMagic had lots of issues with non-Latin scripts.

For now, I'm just upstreaming all our changes to reduce the delta. Later, I'm planning to drop the xserver 1.5 in my xtest builds, so people can test, benchmark and comment. This will give Jim some feedback on which to make a decision. From the patch stream I've seen passing by over the 1.5 timeframe, I expect to see EXA performance improvements, the entity of which is still to be seen. I'll pass the question on to Warren, since he'll end up being the maintainer of the final product in Fedora. Are you ready for OLPC to bang on your drum? Fedora 9 already switched on Xorg 1.5. So at this time amd_drv is broken (does not even build). I offered to fix it by upgrading the rpm as soon as we get a working patchset. I don't know when (and if) we're going to rebase OLPC on F-9, but being ready for Xorg 1.5 would make things easier and allow us to unbranch a good number of RPMs. -- \___/ |___| Bernardo Innocenti - http://www.codewiz.org/ \___\ One Laptop Per Child - http://www.laptop.org/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Accessing PenTablet coordinates from PyGTK
I'm trying to get access to the PenTablet from within a PyGTK application. Since the PenTablet isn't working in the current system, I had to modify xorg.conf to use the evdev driver (as in this example: http://dev.laptop.org/attachment/ticket/2198/new-xorg.conf). Doing this, I can get the PenTablet to work in relative mode to control the core pointer. But what I really want to do is to access the absolute position data from the PenTablet, to be able to draw in a GTK widget independent of the core pointer. I've tried setting SendCoreEvents to false, and then creating a GTK widget and registering for extension events. This allows to receive motion events from the PenTablet, but the x and y values in the event object are inf and nan. Anybody know why this would be? Any suggestions? Apparently there used to be a method gdk.Window.input_get_pointer that would allow you to query the location of the pointer for XInput devices. However, this method appears to be gone in the current version of GTK. Has it moved somewhere? Pat ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Lack of interest on OLPC's part to test this and report on success/failure needs to be resolved ASAP. Rather than lack of interest, there's lack of resources. I'm the only X maintainer left at OLPC, There's plenty more people that could install and test this vanilla driver at Debian, Fedora, Ubuntu and countless other distros that have decided to create OLPC install targets and yet we never heard from them on this issue. If you know of any other folks creating install targets for OLPC, *I'd* love to hear about that. I've found myself stalled while working on a Debian port due to necessary patches not having made their way upstream. Aside from kernel and xorg, there are a bunch of packages that either OLPC is (or was) using forked versions, or that Fedora has patched without the patches getting upstream. Hal, for example.. That makes it pretty darned hard to test an xorg video driver when you have to fight with X to find your input devices.. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Thanks for creating the wiki page! I just added this to the Summer of Code 2008 Ideas page: http://wiki.laptop.org/index.php?title=Summer_of_Code/2008 Micropolis I have a long list of interesting ways to develop Micropolis http://wiki.laptop.org/go/Micropolis, which I have written about on my blog http://www.DonHopkins.com! The source code is on Google Code http://code.google.com/p/micropolis, and I've been working on finishing up all the grunt work that requires familiarity with the code and would be hard for other people to do, to enable other people to work on the higher level stuff that depends on that. There are two Micropolis projects: * The old micropolis-activity which is the original TCL/Tk version of SimCity for Unix, which I ported to Linux and adapted to the OLPC. * The new MicropolisCore C++/SWIG/Python module that I've cleaned up and I have started developing a user interface. It would be best to put effort into developing the new MicropolisCore code for the long term, although there are some small tasks that could be done with the old TCL/Tk code for the short term. -Don Hopkins http://wiki.laptop.org/go/User:Dhopkins Sayamindu Dasgupta wrote: Ok - here's the idea page - http://wiki.laptop.org/go/Summer_of_Code/2008/Ideas Thanks, Sayamindu ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: OLPC.tv and Gnash
The versions of gnash in Ship.* and in Update.1 can't play streaming Ogg videos in a sub-window of a web page yet. That support is in current gnash CVS, and will be in next week's gnash-0.8.2 release, which should be in XO Update.2. However, the standard Browse in update.1 (and perhaps in Ship.1) can play streaming ogg videos, taking up the full screen. Try this URL on yours: http://www.redhat.com/v/magazine/ogg/FUDConWrapup.ogg or http://www.redhat.com/videos/ (click the Ogg links below the Flash boxes) If the maintainer of http://olpc.tv wanted their videos to be viewable on a standard, mass production OLPC, they'd have to transcode them from proprietary codecs (like FLV, which YouTube uses) into the free Ogg Theora video codec. (Then again, olpc.tv's audience may be people who DON'T have an olpc, rather than those who do!) Today is the first I heard of SSS/OLPC. From a brief search engine look, it appears to be a single custom computer built out of a prototype OLPC circuit board. If it plays every Flash 9 movie perfectly, then it's running the proprietary Adobe Flash Player, which OLPC cannot reproduce, support, or ship. I'm happy that the owner of the SSS/OLPC can have fun tinkering with it, but there are hundreds of thousands of people with ordinary OLPCs who we aim to support -- with free software -- in the XO software releases and websites.

Re: Is read_file() always called after an activity __init__?
Hmmm, so if my activity needs it's preferences before it can display anything to the user, potential future lazy loading of the data-store (to try and speed up general activity start-up time) is going to leave folks watching my activity with a blank screen for a lazy while? Ouch. Ahem. The Grand Unified Theory of OLPC was that the datastore/journal were going to entirely replace the filesystem (as far as Activites are concerned). Activities aren't permitted to read/write the ordinary Linux filesystem, according to this theory. If the datastore isn't just as ready, just as fast, and just as available as the filesystem, e.g. for holding tiny little files that rapidly keep the Activity's configuation options, then there's something terribly wrong here.
